Is it possible to put two directory addresses on that line and have the data uploaded to two places at once?The addresses are on two of my domains on the same server.Just trying to move from one domain to the other.Will it do it?

This would "soft link" the second location to the first such that they both point to the same location on the filesystem. That way, your data appears to a user of the filesystem to be in both locations at once. That means you only need to place your Cumulus data in the first location, and it will appear to exist at the second one too.
